Xylobanus elusus. 

 (Plate X. fig. 9.) 



Ater, opacus ; thorace medio areola lanceolata ; elytris quadri- 

 costatis, interstitiis costis numerosis transversis approximatis. 5 . 



Long. 3| lin. 



Hah. Borneo ( Wallace). 



A dull black species, parallel. Thorax transverse, trapeziform, 

 not much retlexed at the sides, with an obscure areolet in the middle. 

 Elytra with the four costee strong ; the numerous transverse costae in 

 the interstices are not so much elevated as the longitudinal costae, 

 and divide the surface into strongly transverse quadrate spaces. 

 The first and second costae are fuscous at the base. 



Xylobanus fumigatus. 



(Plate XI. fig. 1.) 



At-er, opacus ; thorace obsolete septemareolato ; elytris quadri- 

 costatis, costis basi fuscis, interstitiis velutinis, costis numerosis 

 bene approximatis. $ . Long. 3|-4| lin. 



Hah. Borneo ( Wallace). 



This closely resembles X. humilis,' but the areolets of the thorax 

 are not so well defined ; the elytra have the same four strong costae, 

 but the transverse costae are black, less distinct and much closer 

 together, and the interstices have a more wooUy appearance. 



Xylobanus indutus. 



(Plate X. fig. 10.) 



Ater, opacus ; thorace medio areola lanceolata ; elytris quadri- 

 costatis, costis basi fuscis, interstitiis velutinis, costis numerosis 

 transversis bene approximatis. 2 • Long. 4| lin. 



Hab. Sumatra {E. C. Buxton). 



This differs from X. fumigatus in having only a single lanceolate 

 areolet in the middle of the thorax. The interstices of the elytra 

 are very woolly and the transverse costae are rather obscure and 

 very close together. 



Xylobanus intricatus. 



(Plate XI. fig. 3.) 



Fuscus, subopacus ; thorace subnitido, medio antice carina brevi, 

 postice areola angusta lanceolata ; elytris octocostatis, interstitiis 

 costis numerosis transversis minus approximatis. $ . Long. 3 Hn.
